CO2 laser additive manufacturing of multi-layer heterogeneous transparent films using TiO2 and SiO2 nanoparticles

Abstract

CO2 laser additive manufacturing of multi-layer heterogeneous transparent films using anatase-TiO2 and SiO2 nanoparticles (NPs) is reported. The preparation of these films was carried out in two steps; corresponding to (i) evaporation of liquid, and (ii) sintering NPs to form transparent thin films on the quartz substrate (QS). Seven multi-layer films; i.e.,
